OKC Man Charged With Making Casper Threats

A 34-year-old Oklahoma City man is behind bars and faces a federal charge of making a threatening on-line post after allegedly saying he was going to launch a violent attack in Casper.

Glenn Kirkham faces up to five years in prison and a $250,000 fine if convicted.

Investigators believe Kirkham is the man who posted the internet threat that caused Natrona County Schools to be locked down and put the entire city on edge.

According to court documents, Kirkham made the threats on the website 4chan.org. Kirkham allegedly posted the threats at 8:37 a.m. central time on Monday.

Kirkham allegedly started by saying "Watch the news in about 1-2 hours, Casper, Wyoming." According to a federal affidavit, Kirkham went on to say that he would use a revolver, a .22 derringer, kitchen knives, and other weapons to carry out the attack. In the post, he also allegedly wanted to make a point that "primitive weapons" could be just as effective as weapons that some think "should be illegal."

Police first became aware of the threat on Monday morning, and immediately began efforts to find the source. Casper Police first received a call from a man in British Columbia who had seen the post. Others from multiple states including Virginia, Arizona, Washington, Pennsylvania, and Maryland also called.

Authorities then tracked the computer IP address to Oklahoma City and ultimately to Kirkham's apartment.

When FBI agents arrived at the apartment, court documents say that Kirkham knew why they were there, and admitted posting the threats on 4chan.org. Kirkham called the threats an "artistic falsehood" aimed at baiting people with something to let their minds run wild. He also said that he randomly picked Casper in the threat.

Kirkham says he also made a later posting in which he described the first threat as "a work of fiction" and said "only a fool would take anything posted [on 4chan] as fact."

In federal court in Oklahoma on Tuesday, Kirkham was officially charged with "transmitting a threat to injure a person in interstate or foreign commerce." Kirkham's father told affiliate KOCO-TV that his son is a "good kid and has never been in trouble."
